What are the cathode and anode in a fuel cell made from?

The cathode in a fuel cell is typically made from a material like platinum, which serves as a catalyst for the oxygen reduction reaction. The anode is usually made from a material like nickel, which helps facilitate the oxidation of the fuel.


What is reversed conditioning?

The cathode must be made more positive with respect to the anode.


Can the water heater operate without a sacrafical annode?

Water heaters can operate without an anode rod. If tank is not made of steel, then no anode rod is present. If tank is made from steel or glass-lined steel, then anode rod is necessary for long life of tank. Without anode rod, water will rust tank causing leaks and possible failure where tank bursts open and floods house until water is turned off. Anode rods are made of lower noble metals than steel water heater tank. When the two metals are connected together, water reacts with lower noble metal first, so the water dissolves anode rod instead of rusting tank. Anode rods should be checked every two-four years, more frequently when water is softened. Factory-made, gas and electric, steel water heaters come with one or two anode rods installed. Tanks with longer warranties generally have two anode rods. Check manual for specifics. Adding a second anode rod can prolong life of water heater. Ship hulls and propellers, and steel bridges, and other structures that come in contact with water also have anode rods.
